2 claims. (01. 311 107) This invention relates to table tops adapted for use on card tablesand the like to convert a square table, normally seating four persons, to a round table, around which six or more persons can conveniently seat in playing games or in serving refreshments. More particularly, the invention deals with a collapsible table top of the character described, which can be compactly folded into a quarter section, thus taking up a minimum amount of space for shipment and storage. The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate .parts are designated by suitable reference characters in each of the views and, in which:

Fig. -1 is a bottom perspective view illustrating a use of a table top made according to my invention.

Fig. 2 is a perspective view showing the table top on an enlarged scale from that shown in Fig. 1 with parts collapsed into the quarter section.

Fig. 3 is a section on the line 3-3 of Fig. 2 on an enlarged scale.

Fig. 4 is a view similar to Fig. 3, the section being on the line 4-4 of Fig. 2; and

Fig. 5 is a section on the line 65 of Fig. l omitting the table portion.

To illustrate one adaptation and use of my invention, I have shown at ID, in Fig. l, a card table having four legs ii and, at i2, is shown one of my improved round table tops. The table top I2 is formed from four quarter sections which are designated at l3, l4, l5 and [6 in Figs. 3 and 4 of the drawing. These sections can be composed of any suitable material and, in the more economical constructions, will be formed of corrugated-board having upper and lower facings thereon, as indicated at l3, l4, l5 and 16'.

The outer edge portions of all of the sections [3 and I6, inclusive, have binding strips, as indicated at 11, in order to finish and reinforce these edges. In the construction shown, one straight edge portion of each section will be designated by the reference character [8, note Fig. 3, and the other straight edge portion is designated by the reference character 19. At the edge portion l8, the sections [4 and i5 are hinged together, this hinge being formed by two hinge strips 20, 2! in the construction shown. The strip joins outer and edge surfaces of the sections I4 and I5; whereas the hinge strip 2| joins adjacent surfaces. The straight edge ,2 portions Il8 of the {sections 13 and 1.8 have fi i hing strips l1", similar to thesti'ips l'l.

Considering now the straight edge portions 19 of the sections, here it will be noted that two hinge strips 20" 20" are employed which are similar to'the strips 211. The strip '20 hingedly couples the sections I3 and I4; whereas the strip 2i!" hingedly couples the sections 15 and '16. These pairs of sections are further joined at adjacent surfaces by hinge strips, similar to the strip 2!, as at 2|" and 2ft.

.As heretofore stated, the construction shown is of a simple, lightweight and economical construction, but in more expensive types of table tops, different hinge constructions can be employed.

With the structure shown, it will appear that the sections i3 and it can be extended with respect to the sections i4 and 15 on the hinges 20, 20", thus producing a half-round double thickness arrangement of the construction, after which the parts can be extended into the round construction by swinging movement of the sections l4 and [5, one with respect to the other on the hinge 20. As a result of this operation, the corner portions 22 and 22' of the sections l3 and I6 will be disposed in abutting relationship to each other, as indicated in Fig. 1.

I employ on one of these corner portions, for example, the corner portion 22', a U-shaped clip 23 which has a frictional engagement with the edge of both sections l3 and I6 and can normally be retained within boundaries of the corner portion 22', indicated in Fig. 2. However, when the sections are extended, the clip 23 is moved onto the corner portion 22 to lap the joint and thus reinforce and retain the sections I3 and I6 against relative movement.

About centrally of each of the sections l3--l6, adjacent the outer rounded edges thereof, are secured. retaining units 24, all of which are of the same construction and, in Fig. 5 of the drawing, I have shown a section through one of said units. Each unit comprises a thin and relatively soft textured board 25 and a heavier fibre-board 26, both of which have transverse apertures, as at 21, adjacent end portions thereof, through which end portions of an elastic strap 28 are passed.

The strap end portions 29 are brought onto the lower surface of the strip 25 and are secured thereto in the manner indicated in Fig. 5. The strips 25 and 26 are further adhesively secured together, as indicated at 30, and the complete unit is adhesively secured to the respective sections, as indicated at 3|.

It will be understood that the unit 24 is secured to the facing sheet 16 which sheet is, in turn, adhesively or otherwise secured to the body portion of the section [6. The elastics 28 provide a simple method of attaching the various sections to corner portions of the table I in the maner diagrammatiaclly illustrated in Fig. 1 of the drawing. This holds the various sections down firmly upon the table and also retains the table top against shifting displacement with respect to the table. By virtue of the hinge construction employed, the various sections are foldable into the quarter form shown in Fig. 2 which simplifies storage and packaging of the complete table top.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A collapsible card table top, comprising four similar paperboard quarter sections, adjacent side edge portions of the quarter sections being hinged together by strip hinges in such manner as to leave one of the adjacent edges of two sections free, means freely slidable on and bridging peripheral edge portions of said last named free sections where they abut to hold said sections together in forming an extended table top, means on the lower surface of each section centrally intermediate side edge portions thereof for securing the sections to the corner portion of a card table, said last named means comprising a unit consisting of two elongated apertured strips, an elastic strap having its ends extending through the apertures of said strips, said strips being secured together, and means adhesively securing the unit to the lower surface of a section.

2. A round table top of the class described, comprising four paperboard sections having curved outer peripheral edges, each section having upper and lower fa-cings, said sections being hingedly coupled at their adjacent side edges and free at side edges of two sections to dispose said sections one upon the other in collapsing thereof forming a package defined by the contour of one section and thickness of the combined sections, a curved U-shaped clip frictionally and slidably mounted on peripheral edges of said free sections for securing said free sections together, when the table top is in set-up condition, means overlying outer edges of both facings for reinforcing peripheral edges of all of said sections, the hinge coupling between said sections comprising hinge strips secured to upper and lower surfaces of the sections, elastic bands on the lower surface of each section centrally intermediate side edges thereof for securing the table top to a supporting table, and strips adhesively secured to said bands and to the lower surface of said sections for securing the bands in position.
